Dr RK Pachauri

We are pleased to note that Ofcom’s Fairness ruling has vindicated the IPCC’s
claim against Channel 4 in spirit and in substance, and upheld most of the
formal complaints made by those who respect the IPCC process. It is heartening
to see that the review process of the IPCC, and the credibility of the
publications of the IPCC were upheld, as was the claim that Channel 4 did not
give the Panel adequate time to respond to most of their allegations. The IPCC
is an organization that brings together the best experts from all over the world
committed to working on an objective assessment of all aspects of climate
change. The relevance and integrity of its work cannot be belittled by
misleading or irresponsible reporting. We express our appreciation of the
Fairness Committee at Ofcom, and are satisfied with their rulings on this
matter.

Sir John Houghton (FRS)

Chair or Co-Chair of IPCC Working Group I during
the First, Second and Third Assessments

Sir John Houghton provided information that was used in the sections of this complaint relating to
IPCC WG I. He also co-authorised our Fairness complaint on behalf of the IPCC.

The Fairness ruling from Ofcom regarding the Great Global
Warming Swindle programme has exposed the misleading and false information
regarding the Intergovernmental Panel on Climate Change (IPCC) that was
contained in that programme and that has been widely disseminated by the climate
denying community.

The integrity of the IPCC’s reports has therefore been
confirmed as has their value as a source of accurate and reliable information
about climate change.

The IPCC latest report of 2007 states clearly that global
warming is happening and explains the urgent action needed to reduce global
emissions of greenhouse gases (especially CO2), if the most serious consequences
of climate change are to be avoided, due for example to sea level rise and to
increased frequency and/or intensity of heat waves, floods, droughts and storms.

It's very disappointing that Ofcom hasn't come up with a
stronger statement about being misled, I know hundreds of people, literally
hundreds, who were misled by it - they saw it, it was a well-produced programme
and they imagined it had some truth behind it, so they were misled and it seems
Ofcom didn't care about that.

Professor Carl Wunsch

Professor Wunsch provided documentary evidence
that was used by the authors in the sections of the complaint covering his
interviews in the film.

Anyone who wants to understand why much of the scientific
community reacted so furiously to The Great Global Warming Swindle should read
the Rive, Jackson, Rado et al. complaint to Ofcom. This document lays out in
detail the large number of apparently deliberate distortions contained in the
film, distortions that no credible scientist would accept as part of normal
scientific debate. Channel 4 broadcast a political propaganda film masquerading
as a science documentary. As Rive et al. make clear, the film exaggerates the
credentials of its purported “experts”, changed published data to suit its own
ends, and in general took a complicated scientific problem, over-simplified and
changed the evidence, while suppressing all contrary views from the true
experts. In real science, practitioners work in good faith, honestly describing
contrary points of view, weighing the evidence, and discussing what is more and
less certain. The Great Global Warming Swindle did none of these things.

Professor Martin Parry (OBE)

Co-Chair of IPCC Working Group II for the Fourth
Assessment, and Visiting Professor at the Centre for Environmental Policy,
Imperial College, University of London

Professor Parry peer reviewed our submission to Ofcom
(which is referred to in the Fairness Ruling), in response to Channel 4’s
reply to our Fairness complaint. He also co-authorised our Fairness complaint
on behalf of the IPCC.

People and policymakers need to have confidence in the
science of climate change. The reputation of the IPCC as the source of
dependable and high quality information has been fully upheld by
Ofcom’s Fairness ruling. Channel 4’s Great Global Warming Swindle was itself a disreputable
attempt to swindle the public of the confidence it needs in scientific advice.

Professor James McCarthy

Co-chair of the IPCC Working Group II (2001);
Lead Author for the recently completed Arctic Climate Impact Assessment; and
Professor of Biological Oceanography at Harvard University.

Professor McCarthy peer reviewed those sections
of this complaint that relate to IPCC Working Group II and to the epidemiology
and entomology content of the IPCC WG2 reports. He also co-authored some
sections, and peer reviewed others, of our submission to Ofcom (which is
referred to in the Fairness Ruling) in response to Channel 4’s reply to our
Fairness complaint.

The fundamental science that underpins this understanding of
climate has been vetted by pre-eminent professional societies of geophysicists,
meteorologists, oceanographers, and academies of science worldwide, in addition
to the IPCC. All of their summary statements are similar. A good example is that
of the American Metrological Association: “Despite uncertainties, there is
adequate evidence from observations and interpretations of climate simulations
to conclude that the atmosphere, ocean, and land surface are warming; that
humans have significantly contributed to this change; and that further climate
change will continue to have important impacts on human societies, on economies,
on ecosystems and on wildlife through the 21st century and beyond”.

By analogy, think of the official position statements of the
academies of medicine as well as associations and societies of scientists and
physicians who devote their lives to the study, prevention, and treatment of
lung and heart disease, that cite the evidence that strongly links tobacco
smoking to these diseases. Can one find the odd physician or researcher who says
that he is not yet convinced of this cause and effect relationship? Of course.
After all, some people smoke tobacco all their lives, and die of other causes at
advanced age. Think of a film that interviews a group of people who hold this
position – a position that flies in the face of an enormous body of good science
– that states, as a fact, that this group of interviewees represents the only
honest scientists, and claims, moreover, that “you are being lied to” by every
scientist who holds the mainstream position. Such a production would be
analogous to what Martin Durkin has done on Channel 4.

While condemning crass distortions of Durkin and Channel 4, we must also
encourage public media efforts that truly help the non-scientist understand
climate science and the consequences of inaction. The public deserves to know
about the true uncertainties in climate science, and as importantly, the range
of options that will enable us to dramatically reduce both our dependence on
fossil fuel combustion for energy production and other greenhouse gas producing
activities.

I welcome Ofcom’s ruling which demonstrates that
The Great
Global Warming Swindle was unbalanced and totally misrepresented the scientific
consensus on the role of human activities in causing the global warming. The
program inaccurately portrayed the scientific evidence, was not impartial, which
a documentary should be, and was unfair in its treatment of the IPCC and leading
scientists such as Sir David King.

Human-induced climate change is an environmental,
development and security issue. Attempts to undermine the clear scientific
consensus on this issue are misleading and detract from the urgent challenge
that the world is facing – namely to reduce greenhouse gas emissions
sufficiently and rapidly enough to avoid dangerous levels of climate change in
the future. The Great Global Warming Swindle did a major disservice to the
public at large and tried to undermine the scientific basis upon which
governments and the private sector are using to cost-effectively address one of
the greatest challenges the human race has ever faced.

The IPCC, which was established by the United Nations in the
late 1980s, is the world’s authoritative voice on the scientific and technical
knowledge regarding climate change. The IPCC engages thousands of the world’s
best experts to prepare and critically peer-review the scientific and
technical evidence and is a non-political body addressing a very political
issue. It is used by governments to inform policy and by the private sector to
inform investment decisions.

The bottom line is that there is no doubt that human
activities are responsible for the observed changes in climate over the past 50
years and that we need to act urgently to avoid dangerous climate change. We
need to reduce the emissions of greenhouse gases and adapt to the changing
climate.

I am pleased that Ofcom recognized the serious inaccuracies
in the Global Warming Swindle and has helped set the record straight.

Oceanography Centre, University of Southampton, and Deputy Director of the
Tyndall Centre for Climate Change Research

Professor Shepherd peer reviewed our entire complaint

This Ofcom ruling is very strange indeed. It upholds most of
the complaints relating to fairness to individuals and organisations, and some
of those relating to impartiality and mis-representation of the facts.
Nevertheless, it concludes that this did not lead to the audience being
materially misled so as to cause harm or offence! This is extraordinary, because
this programme was essentially propoganda, and a travesty of what a science
documentary should be. It was extremely biased, and misrepresented the facts on
almost every issue that it raised. It also distorted or misrepresented the work
of the IPCC, and the views of several serious scientists who were interviewed.
It presented a very confused and misleading message, especially by mixing up
some true and uncontroversial statements with many false or misleading
implications drawn from them (see my critique posted at
http://tinyurl.com/2jwx82).

As one of the many people who complained about this
programme, I am very pleased that Ofcom have now upheld many of these
complaints, but astonished that it did not find C4 and the programme makers
guilty of misleading the public. Public policy on climate change depends
crucially on its scientific basis, and this is far too serious and important for
it to be mis-represented as it was by this programme. I hope that the ruling
will prove to be sufficiently adverse that the programme will now fade away into
well-deserved obscurity.

Epidemiology and Population Health, in The Australian National University

Professor McMichael peer reviewed those sections
of this complaint that relate to IPCC Working Group II and to the epidemiology
and entomology content of the IPCC WG2 reports

The Great Global Warming Swindle contained many flagrantly
inaccurate and distorted claims regarding the IPCC, and was an attack on the
diligent work that thousands of scientists perform to accurately assess the
current state of scientific knowledge. It is crucial that policy makers have
access to such an accurate assessment and that the public has confidence in the
impartiality and honesty of the work that mainstream scientists do. The film
therefore represented an extreme low point in irresponsible journalism, and I am
pleased that most of the Fairness complaints on behalf of the IPCC were upheld
by Ofcom.

Dr Benjamin Santer

Convening Lead Author in the IPCC’s Second
Assessment and an Atmospheric scientist at Lawrence Livermore National
Laboratory

Dr Santer co-authored a sections of our submission to Ofcom
(which is referred to in the Fairness Ruling) in response to Channel 4’s
reply to our Fairness complaint.

Anyone who has children has an investment in the future –
an investment in the kind of world we leave behind for our descendants. In order
to take informed decisions on “what to do”
about the problem of human-induced climate change, and hence on our climatic
legacy, we need an informed electorate. The media play a crucial role in this
process of disseminating information to the general public. They are a trusted
source of information. Given their privileged position, they have a
responsibility to “get the science right”, and to get the facts right,
particularly on matters of significant national and international concern.

Unfortunately, Channel 4 abdicated their journalistic
responsibility to give a fair and balanced picture of the current state of
climate science. They presented a completely false picture of a community of
climate scientists actively engaged in duping the rest of the world. Channel 4’s
Great Global Warming Swindle focused on selling a bizarre conspiracy
theory to the British public, rather than on doing the diligent, painstaking
reporting that would have been necessary in order to improve public
understanding of a complex scientific issue.

Together with many of my scientific colleagues, I have spent most of my
career trying to understand the nature and causes of climate change. It is a
difficult job. There will always be significant uncertainties in our work, since
we are performing a planetary-scale experiment without a control. Nevertheless,
we now know beyond a shadow of a doubt that human activities have affected the
Earth’s climate. By burning fossil fuels, we have changed the chemical
composition of the atmosphere. These human-caused changes in atmospheric
chemistry explain most of the surface warming we have observed over the 20th and
early 21st centuries. We are no longer passive observers of the physical changes
in the land, ocean, and atmosphere, as we were for millions of years. Humanity
is now an active agent of change in Earth’s climate. This is the story that
Channel 4should have told the British public.

On a personal note, I am extremely gratified by
Ofcom’s decision on the Fairness complaint.
Channel 4 failed to provide an accurate account of the role I fulfilled 13 years ago as Convening Lead Author of a key chapter of the IPCC’s Second Assessment Report.
Channel 4 cited erroneous criticism of that chapter by a prominent
anti-climate change lobbyist (Fred Seitz), without discussing the detailed responses to Seitz’s criticism that were supplied by myself, the IPCC, and numerous others. The
Ofcom ruling sets the record straight by noting that Channel 4’s account of this incident was one-sided and misleading.

Atmospheric Research in Boulder, Colorado

Dr Trenberth peer reviewed parts of our submission to Ofcom
(which are referred to in the Fairness Ruling) in response to Channel 4’s
reply to our Fairness complaint.

Global warming does not mean that it steadily warms
everywhere. With all the complexity in the climate system, and all the natural
variability related to weather and El Niño, it is easy to point to things that
might appear to be at odds with the warming of the planet. Uncertainties abound as to how climate change will play out, but the fact that global warming will
continue is not one of them. Responsible journalism should recognize the
comprehensive, thorough, open process of the IPCC and its state-of-the-art
reports, which by their very nature are inherently conservative. To do
otherwise, as Channel 4 did in its The Great Global Warming Swindle on 8
March 2007, is irresponsible.

The signs of human-induced warming abound, and at times,
such as in the 2003 summer heat waves in Europe, they can be devastating. The
reason this is a crisis is not so much because of the current climate, but
rather the climate changes that are guaranteed to continue for decades, at
least, and there is no coherent concerted global action to slow these changes
down or prevent them, let alone plan for the consequences. The crisis is one of
inaction. Informing and educating the public about these aspects should be a
part of the role of the media, and playing up views of a few individuals who
often have vested interests is simply not responsible at best and reprehensible
at worst.

On how storms are affected by climate change

An area of particular controversy is the attribution of
severe storms to global warming. While individual storms cannot be thus
attributed, the increasing frequency and/or average intensity of some types of
storm may be linked to climate change. This possibility is clearly denied by
Professor Richard Lindzen, who points out that “… the main source of weather
disturbances is the temperature difference between the tropics and the poles …”,
and argues that warming will lead to “less storminess”. While broadly true, this
statement refers to the source of extra-tropical “cyclogenesis” – e.g., the
formation of large depressions that track eastwards towards to UK, most often in
autumn and spring. The truly catastrophic storms are the hurricanes, cyclones
and typhoons that occur in the tropics, and the remnants of such storms that
sometimes reach the extratropics, with further adverse impacts. The formation
and sustenance of such storms is strongly linked to the state of the regional
ocean and atmosphere – winds, humidity, ocean warmth – each of which may change
with climate, either naturally or under anthropogenic influence. Summer
precipitation in the mid-latitudes is further affected by other critical local
factors, such as the position of the jet stream. It is not yet clear how the jet
streams will respond to global warming.

On the misleading history of the IPCC

The history of the IPCC as recounted by the Narrator is
inaccurate and intentionally misleading. Following remarks of Nigel Lawson, the
impression is given that Mrs. Thatcher provided the impetus for the IPCC around
1988, with political motives. In fact, the IPCC was established in 1988 by the
World Meteorological Organization (WMO) and the United Nations Environment
Programme. These organizations, together with the International Council for
Science, had individually and collectively organized conferences in 1979 and
1985, which expressed concern about the human impact on the climate. They
subsequently established the Advisory Group on Greenhouse Gases to “ensure
periodic assessments of the state of scientific on climate change and its
implications.” This process culminated in the IPCC, which was proposed in the
10th Congress of the WMO in May 1987, before its establishment in 1988. These
international developments long pre-date Mrs. Thatcher’s growing concern about
climate change, which was first made public in a speech to the Royal Society in
September 1988.

Professor Alistair Woodward

Head of the School of Population Health, Medical and Health Sciences, University of Auckland.
Lead Author for the 3rd and 4th Assessment Reports of IPCC Working Group II.

Professor Woodward co-authored those sections of this complaint that
relate to IPCC Working Group II and to the epidemiology and entomology content of the IPCC
WG2 reports.

As part of its attack on the integrity of the IPCC,
Swindle argued that the link between global warming and malaria had been
greatly over-stated. The programme also claimed that the IPCC did not include
the “truly scientific literature” on the topic, and that one particular
scientist, Professor Paul Reiter, who was interviewed on Swindle, had needed
to threaten legal action in order to resign from the IPCC.

The case made by Swindle is based on selective and
inaccurate quotes from the IPCC reports. The programme simply omitted critical
phrases from key statements in an effort to make the conclusions of the IPCC
appear more extreme than they truly are. The programme included no explanation
of what it meant by the “truly scientific” literature, nor could it point to any
particular relevant scientific publication that the IPCC had failed to include.
And the claims about resigning from the IPCC had no documentary evidence, and
betrayed a serious lack of knowledge of how the IPCC actually works.

Ofcom has found that the IPCC was treated unfairly by the
makers of the programme. Global warming is the biggest environmental issue of
this century, and it demands a more comprehensive and carefully constructed
analysis than Swindle. In my view, Channel 4 has failed to meet the standard
one would expect of a socially responsible broadcaster, and it is most
heartening to see that Ofcom is of a similar mind.

Dr Jonathan Köhler

Economist, and a Senior Research Associate with the
Tyndall Centre for Climate Change Research

Dr Köhler co-authored the development economics and renewable energy sections of the
complaint.

The Great Global Warming Swindle programme claimed
that environmentalists want to stop economic development in Africa and that “Western
governments have now embraced the need for international agreements to restrain
industrial production in the developing and developed world.”

There is no-one in the environmental movement who says that
the poorest countries of the world should have their access to energy
restricted. The reason for this is that the poorest countries have very low
emissions. Even if they do develop using coal power, they will not contribute
significantly to climate change. It is the OECD nations, EU, US Canada, Japan,
Korea, Taiwan, Russia; and the newly industrialising countries China, India,
Brazil and Mexico, which have large greenhouse gas emissions and which will have
to reduce their emissions (but not their economic growth by any significant
amount).

There are no international agreements, either in place, or
being considered, to restrain industrial production, either in the developing or
the developed world.

In economic debates about climate change, it is now
understood that economic development and climate policy complement each other:
there is no trade off between them. On the contrary, the Stern Review
demonstrates that

…an upper bound for the expected annual cost
of emissions reductions consistent with a trajectory leading to stabilisation at
550ppm CO2e is likely to be around 1% of (World) GDP by 2050 … (1% of World
GDP)…… is significant, but is fully consistent with continued growth and
development, in contrast with unabated climate change, which will eventually
pose significant threats to growth.

(Stern Review, Executive Summary, page xiii).

Monica Samec

Renewable energy consultant and Advisor for the
Council for Renewable Energy in Nigeria

Ms Samec co-authored the renewable energy and
development economics sections of the complaint.

For these filmmakers to dismiss renewable energy’s
utility to developing nations based the simplified claim that it is too
expensive for the world’s poor and to
justify that claim with one improperly designed solar system makes a mockery out of the concept of a documentary. The costs
of renewable energy and the price of energy for the world’s poor vary
greatly. There is a growing overlap of situations in which renewable energy
can provide cost-effective energy solutions for developing nations. I hope,
in the future, people will take time to understand the complexities of these
topics before issuing ill-informed generalizations.

It is unbalanced and damaging that the film’s position
ignores growing evidence that poor populations will experience disproportionate
negative impacts from climate change. We now have a first generation of
practical policies, informed by decades of science, to assist developing nations
with climate change adaptation and sustainable energy implementation. For
example, the Clean Development Mechanism allows industrialized countries to
assist in making clean energy affordable to developing nations as a way of
meeting emission reduction targets. Climate change policies that are being
debated right now have the potential to further accelerate the financing of
clean energy in ways that benefit the world’s poor. It is in their interest that
we learn about and support such policies rather than trivialize them.

University

Dr Watson peer reviewed the development economics and
renewable energy sections of the complaint

The assertion in The Great Global Warming Swindle
that rich countries expect poor people in developing countries to only use
inefficient, expensive energy sources is absurd. Furthermore, the claim that
developed countries wish to ‘restrain industrial production’ in developing
countries – or that they are likely to in the near future – is plain wrong.
As many of those involved in negotiating international agreements to tackle
climate change recognise, these agreements must include the legitimate wish
of the world’s poorer countries to develop.

Dr Julie Doyle

Principal Lecturer in Media Studies, University of
Brighton, UK

Dr Julie Doyle co-authored the sections of the
complaint relating to media coverage of climate change and peer reviewed the
section of the complaint related to the representation of environmental groups.

In light of the Ofcom ruling regarding The Great Global
Warming Swindle, I would encourage the public to read our complaint to see
for themselves the wealth of evidence we have compiled to support our criticisms
of the programme.

We disputed the claim made in The Great Global Warming
Swindle that the media regard climate change as “an undisputed fact”. Whilst it
is certainly true that there has been an increase in news media coverage of
climate change in the UK in recent years, we argued that it has taken a very
long time for this issue to be covered by the media. This has been in stark
contrast to the scientific consensus on climate change since the mid 1990s. We
pointed out that the journalistic norm of ‘for and against’ has actually led to
a biased representation of climate change in the media, where climate sceptics
have historically been given an equal weighting and voice with climate
scientists. We also disputed the claim made in The Great Global Warming Swindle
that media coverage of climate change has been “fantastically apocalyptic” and
“hysterical”. We argued that the media are now exploring the many ways that
climate change is currently being lived with, or adapted to, through diverse
areas such as gardening and food, to economics and business. The further
assertion in The Great Global Warming Swindle that its contributors have been
ignored by the media or treated as “heretics” was a claim that we also
challenged. We argued that all of the contributors have enjoyed privileged
access to the prestige press in the UK and the US. This high level of coverage
has been disproportional to their standing within the climate science community,
resulting in the public being given a distorted view of their credibility and
position within climate change science.

Co-Director of the Cambridge Media and Environment Programme

Dr Smith peer reviewed the sections of the complaint
relating to the media’s coverage of climate change

Within the protective bubble of media commissioning it is
easy to see why Swindle looked like a good idea: it was provocative, naughty and
counterintuitive. It gave voice to outcast experts, defied groupthink and
surprised the audience. But pop the bubble, step outside and talk to the
numerous and broad climate change science and policy community and it is viewed
as one of the most unhelpful pieces of programme making about a science topic
that anyone can remember. Britain had established itself as a leader in the
extent and quality of public debate about climate change but the Swindle
programme dented that. It is a clear example of how the media’s desire to appear
edgy and probing can leave everyone involved in a commission looking at best
foolish and dated.

Ofcom’s ruling is a vindication of the concerns that we,
and many others, had with The Great Global Warming Swindle documentary.
Global warming is a topic worthy of public debate, but C4 and TGGWS have
done a public disservice by presenting misinformation and unfairly
representing members of the climate change community. Climate change
involves enough interesting topics and uncertainties to set up an engaging
discussion – without the need to resort to distortion, misinformation,
conspiracy theories, and mud-slinging. C4, as such, have missed a great
prime-time opportunity to educate the public, as per the public service
commitment mandated by their broadcasting license.

My hope is that this ruling will dissuade schools and other
broadcasters from screening TGGWS in future. My hope is that it also encourages
people to educate themselves, and engage themselves in the discussion about
global warming. The IPCC summaries are a good starting point – and why not
contact the climatology department at your local university?
